The match at Bloomfield Road will now be played on Sunday 13 November, with a 4pm kick-off.
Blackpool game to be televised
The game will see Brian Laws' United side come up against the Seasiders, now managed by Colin Hendry.
The ex-Scotland international almost took over as Iron boss a year ago, but a boardroom coup saw Laws reinstated, and Hendry took the Blackpool hotseat last summer.
The match takes place on an international weekend, hence the kick-off time as no Premiership sides are in action.
